الحمل الحراري في حيز مفتوح بوجود فيض مغناطيسي
Abstract
In this paper magneto hydrodynamic (MHD) natural convection flow of Cu–water nanofluid in an open
enclosure is investigated numerically using lattice Boltzmann method (LBM) scheme. The effective thermal
conductivity and viscosity of nanofluid are calculated by the Maxwell–Garnetts (MG) and Brinkman
models, respectively. In addition, the MDF model was used for simulating the effect of uniform magnetic
field. The influence of pertinent parameters such as Hartmann number, nanoparticle volume fraction,
Rayleigh number and the inclination of magnetic field on the flow and heat transfer characteristics have
been examined. The results indicate that the absolute values of stream function decline significantly
by increasing Hartmann numbers while these values rise by increasing Rayleigh numbers. Moreover,
the results show that the solid volume fraction has a significant influence on stream function and heat
transfer, depending on the value of Hartmann and Rayleigh numbers
